One mushroom isn't enough, most functional mushroom drinks use one mushroom, Fungi Fusion has three (Lion's Mane, Cordyceps, Reishi)
What's in every can

Three fruiting body extracts, labeled, dosed, and disclosed.

Lion's Mane fruiting body
The Shaggy One
Lion's Mane
900mg

A shaggy white mushroom used in traditional practices for centuries, added here as a fruiting body extract. At 900mg per can, it's the biggest dose in the blend, not a "fairy dust" sprinkle.

Cordyceps fruiting body
The Mountain One
Cordyceps
700mg

A fruiting body extract with a long history in traditional Himalayan and Chinese herbal practice. 700mg is a meaningful dose, not a trace amount on the back of the can.

Reishi fruiting body
The Queen
Reishi
400mg

Called the "Queen of Mushrooms," Reishi has been part of traditional practices for centuries. It's a fruiting body extract at 400mg, a real, considered dose, and we list it on the front of the can.

One mushroom vs. three.

The typical functional mushroom drink leans on a single mushroom. We disclose all three, with milligrams listed on the front of the can.

"We list every milligram. The other guys won't."

Functional mushroom drinks have a labeling problem. Most brands wave a generic "proprietary blend" sticker and hope you don't ask questions. We took the opposite path.

Three-mushroom blend reviews from real Happie drinkers.

★★★★★

"Most adaptogen seltzers just stick one mushroom on the label. Happie actually lists three, with the milligrams. That alone made me try it. The Lion's Mane focus is real."

★★★★★

"I was tired of brands hiding behind a 'proprietary blend.' Happie shows 900mg Lion's Mane, 700mg Cordyceps, 400mg Reishi right on the can. Refreshing, literally and figuratively."

★★★★★

"The combo of three mushrooms is what sold me, focus from Lion's Mane, clean energy from Cordyceps, calm from Reishi. Other drinks I tried only had one and the effect was forgettable."
